Original application filed November 18, 1908, Serial No. 463,285. Divided and this application filed December 18, 1911.

To aZZ whom it may concern:

Be. it known that I, JULIUS ALsBERo, a citizen of the United States, residing at the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and useful Imp1'ove i shall be capable nents in Insulators, of which the following is a full, clear, and exact specification.

My invention relates to improvements in means for supporting electrical conductors of the type shown in my prior United States Patents, Nos. 1,006,040; 1,006,041, and 1,006,042, dated October 17, 1911, and in my application for Letters Patent of the United States Serial No. 463,285, filed November 18, 1008, of which this application is a divisional application.

' Further, said invention has for its object to provide a simple, efficient and durable insulating supportcomprising an insulating member and a protector therefor composed of a tubular member, and a separate protecting hood adapted to be secured to said tubular member.

to provide an insulator comprising a tubular protecting member formed of insulating material and a separate hood or protector which may be made of insulating material, or any other suitable material which may or may not be treated to render the saine insulating, as desired.

Further, said invention has for its object to provide an insulator having its several parts so arranged and constructed that the same may be nested or packed within small compass for storage or shipment, and which of easy assembling when it is desired to attach the same to a suitable support to suspend a conductor.

Further, said invention has to its object to provide an insulator comprising an in. sulating element proper and a series of protecting sections which may be readil in creased or diminished to form a tubular protector of any desired length to surround sum No. 666,392.

0 the insulating element, and which protecting sections may be easily provided with protecting hoods of any suitable size or kind, as the conditions of service may demand.

To the attainment of' the aforesaid objects and ends, my invention consists in the novel details of construction, and in the connection, combination and arrangement of parts, hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings forming part of this specification, I have shown one form of insulator constructed according to and embodying my said invention, the same being shown as a central vertical section.

In said drawings, 5 designates a supporting arm and 6 a flexible insulating member formed in the shape of a rope composed of strands of insulating material. The upper end of said insulating member is spliced to the body portion thereof to form a loop 7 having a thimble 8 therein adapted to receive the hook 9 of a bolt 10 secured to said supporting arm 5 by a nut 11. The lower end of the insulating member 6 is frayedout and secured by cement, or'other suitable medium, within a conical socket 12 provided at its lower end with a loop or bale 13.

14 denotes a clamp provided with a hook or eye 15 for securing or bale '13 at the lower end of the insulating member 6, and 16 denotes an electric conductor secured in said clamp 14'.

17 and 18 denote tubular. protecting sections preferably madev of glass, porcelain or other suitable insulating-material and arranged one upon the other and surrounding said insulating member'6. The protecting section 18 is provided at its lower end with an enlarged recessed shoulder 20 at the base of said to rest upon the upper, conical socket 12 secured to the lower end of the insulating member 6, and at its uprecess adapted portion 19 having a reduced end of the per end said protecting section 18 is provided with an outwardly projecting bead or rim 21, and an inwardly projecting bead or rim 22 adapted to contact with the insulat-' ing member 6 to hold the latter properly centered within said projecting section 18. The lower end of the projecting section 17 is also provided with an enlarged recessed end 23 which is a apted to receive the upper end of the protecting section 18, and

roe

upon the outersurfece' of said section 17, above said enlarged tion 23, is provided en ennu "bead 25 denotes an inwardly proje' ng arranged at the upper end protecting section 1?, which els maintain the insulating iner centered Within said 'protec 26 denotes a conical protecting of glass, porcelain or nietsh or able material or comhinotions 0,. teriel, The said protecting section is pro-vi ed upon the inner side of its base with a socket adapted to receive the socket p the protecting section 17. The protecting hood 26 is secured to the lower end of the tubular protecting section 18' and upon the socket portion 23 thereof b; cement, other suitable securing means 285- t denotes similar pnotecting hood dispos above the upper end of the protecting section 17 end the insulating member 3 and secured rigioly in position upon the bolt against the under side of the arm It will be noted that the tubular protecting sections 17 and 18 are flexibly united Where the lower socketed portion 23 oi? the section 17 rests upon the upper end of the section 18. VViien it is desired to render the protecting sections rigidly connected, it merely becomes necessary to introduce cement, or other suitable securing medium in --the socket portion 23 below the bend or riin 1 at the upper .end of the tubular protecting section 1.8, thus render the several protecting sections with eir protecting hoods ri 'id and surrounding the insulutii'igmember 6.

It 'Will be noted that by menus of my improved construction, I am enabled to readily provide an insulator composed of u pluru 't V of tubular protecting sections with protcctmg hoods of various sizes and diameters, us

may be required. This, are eneb1ed to so coinplish, by reason of tie tact that the tecting hoods, regardless of their s provided with suitable sockets and 0 whereby the some may be secured to ends of thetubulsr protecting sections Having thus described any invention glint I claim and desire to secure by Letters atent, is;
